I did the last update last week on the Inspire 2 and after having it completed perfectly, the landing gear refused to lower to travel mode.

Since that day, i cannot move my landing gear anymore.

I've tried to activate the landing gear while flying and tried every combination of manual or automatic but nothing happened, it stays stuck at the lower position and software thinks its upper position.

THe message i have on the Go App 4 is " Failed to lower or pack up landing gear..."

I'am in contact with DJI and they say because it cannot enter the transport mode, it cannot travel safely from where i live to where it can be repaired. (Réunion ISland to Germany / 11 000 km by plane)

Problem solved ! I think i have forced the wrong way on the screw beneath the I2 and it was then really hard to turn.

AERISRUN, it is so good to hear the problem got sorted out, we are happy for you.
Please make the aircraft exit travel mode to do the firmware updating, here is the tutorial video for your reference:
